I'm afraid the Series 751 can't install in the kind of jamb liner you've described. If you have a 15-104 friction shoe, then that means your spring is built into the jamb liner; in other words, the jamb liner is functionally the balance itself. You won't be able to install a different type of balance inside of it. Since these are wood windows, I recommend contacting a local mill work. They should be able to set you up with new jamb liners entirely. |

Unfortunately, we're not able to supply the springs that go in this kind of window. The issue is that the springs are made built into the jamb liner; in effect, the jamb liner is the balance itself. Therefore that is what you will need to replace. My suggestion is to contact a local mill work that still makes wood windows. If you bring them your sash and one of the old jamb liners, they should be able to make you new ones, spring and all. |
